indicates a cross arm of bowed format-ion having the extremities-thereofupwardly projected toward the ceiling of a room. A shaft 11 having ahook extremity 12 upon, its u permo'st end lockingly engaged within t eeye 13 of a screw eye or support 14, is jours naled at its lowermost endwithin the central portion of the bowed cross arm 10'; A channel member15 inverted to dis we the bottom thereof flush against the un' er sideof the cross arm 10 and to accommodate the adjacent nut equippedextremity of the shaft 11 carries a pulley wheel 16upon a ivot pin'l7disposed between the side wa s thereof to one side of the verticalcenter thereof; It will thusbe noted from the foregoing description andaccompanying drawings that the cross arm and channel member may rotateasa unit independently of and upon theshaft 11:v A

7 pin 18, carried by the bottom of the channel member 15'and embeddedfor an appreciable portion of its length within the immediate surface ofthe cross arm 10, is.v designed to prevent distortion 6f the channelmember 15 whereby the pulle' wheel 16' will be constant- 1y aligned witht at of a companion pulley wheel 19 carried at an appropriate point inthe length of the cross arm 10. A double pulley 20 telescopicallyassociated with the shaft 11 and fixed thereon by a cross pin 21 isdesigned to receive the. wrappings' of a cord 22 upon the lower pulleysection thereof as same is trained over the pulleys 17 and 19'. I p

Pulley wheels 23, constructed after the manner of the aforementionedpulley wheels and disposed within bifurcations in the extremitie's ofthe cross arm, train or otherwise direct cords or ropes 24 thereoverhaving con nection at their uppermost ends with the upper pulley sectionof the multiple pulley 20, said cords beingwrapped in oppositelydisposedrelation Miniature" aeroplanes or rep-j resentations thereof,such as indicated at 25 are carried upon the de ending ends of the cords24 beyond thepul'leys 23 in the manner suggested in Figure I ofthedrawing's;

v From the description thus far, it is understood that theKaer pIanes'25 in andof their awe Wei-gm win descefid from the Figure 1 position asthe cords 24 are unwound from the upper section of the multiple pulley20 and swing or otherwise rotate the cross arm 10 in a clockwisedirection. During the descending rotary motions of the planes 25, thecord 22 trained over the pulley wheels 16 and 19 respectively will bewound up upon the lower pulley section. The weight 26 carried adj acentthe lowermost extremity of the cord 22 is not sufficient in avoirdupoisto equal the combined weight of the two planes but will materiallyrestrict progress of flight to such an extent that the rapidity ofascent or descent will be retarded to insure longer flights in bothdirections.

As mentioned previously, it is also my intention toprovide a form ofplane ascending apparatus which will not only effect such function butwhich will also become automatically disengaged upon the occasion of theplanes having reached the predetermined destination whereby one moreflight, that is a descending one, will be effected unaided by theoperator of the game. This automatic plane ascending and hook offmechanism primarily resides in the attaching of a ring of theconstruction shown as at 27 in Figures 1 and 3 of the drawings. The hook01f element per se, indicated as at 28, preferably in the formation of avariety of monkey having its tail 29 curved after the manner of a hoopand its two arms extended above its head with both hands claspedtogether to provide a form of hook 30 for accommodation within the ring27. The hands of the monkey are inserted within the ring and hookedthereon when the planes have landed and the cord 22 is wound upon thelower section of the multiple pulley 20. When the monkey is released ofthe hand of the operator and allowed to descend while the planes areascending, it is to be noted that the tail 29 upon being brought intoengagement with a floor surface or the landing field will rock themonkey and cause same to occupy the Figure 1 position'whereby the handswill be released from the ring 27 and the planes will then descend andland. The bowed form of cross arm not only facilitates disposing of theentire apparatus closer to the ceiling whereby longer flights may bemade but the respective pulleys will also be aligned to such an extentthat the cords may be most efiectively wound and rewound.

From the vertical sectional view shown in Figure 3 of the drawings, theespecial construction of the multiple pulley 20 is ex hibited. Thecharacteristic of beads 31 formed upon the inner sides of each of theend flanges of the respective spool sections will serve to prevent thewinding ofthe cords in such manner that same will bind or restrictflight of the aeroplanes.

The modified form of my invention disclosed in Figure 4 of the drawingscomprises essentially the general characteristics of the preferred formand closely follow same in every respect save for the channel member 15.Instead of employing the channel member 15, I make use of the pulleywheel 16 and dispose same within the bowed cross piece in a mannersimilar to that of the mounting of the pulley wheel 19. A bar, such asindicated at 32, having attaching rings 33 upon its ends and secured tothe adjacent extremities of cords 34 oppositely wound upon the lowersection of the multiple pulley 20, is also provided with a ring 35 at anintermediate point in the length thereof to facilitate accommodation ofthe clasped hands of the monkey. The bar 32 is obviously theequivalentin weight to the ball 26 and ring 27 employed in the preferred form.

It may be also desirous to provide a form of stand for the apparatus asshown in Figure 5 of the drawings where chandeliers and other lightingfixtures might interfere with the proper functioning of the aeroplanes.Said stand is preferably in the nature of a tube, indicated as at 35,having a floor flange or base 36 secured upon the lowermost end thereof.A pipe section or standard 37 slidably and adjustably mounted within thetube 35 and retained at any desired height by a stop collar 38,including a set screw for the purpose, and seated upon the upper end ofthe tube 35. A shaft member 39 constructed after the manner of the shaft11, employed in the other forms of my invention and carrying a similarshape and type of hook 40 upon the uppermost end thereof is rigidlyfitted or otherwise connected with the uppermost end of the standard orpipe section 37 through the employment of a bushing 41. The standard 37,bushing and shaft are held as a unitary structure through the employmentof a set screw 42 threadedly engaging horizontally of and within theimmediate portion of the aforementioned standard.

Independent or separate pulleys 43 are arranged and fixedly secured atintervals upon the outer exposed portion of the shaft 39 and uponopposite sides of a cross arm, generally designated asat 45. Bearing orspacing washers 46 loosely connected with the shaft 39 and bearingagainst the immediate oppositely disposed surfaces of the cross arm andthe adjacent ends of the respective pulleys 43 and 44 are designed topermit freedom ,of movement to the latter mentioned arm.

The intermediate portion of the cross arms 45 is upwardly bowed wherebylongitudinal passageways 47 in the arm proper may be lined up uponopposite sides of the lowermost pulley 44. Vertical passageways 48 alsoincluded in the cross arm have. their uppermost ends disposed adjacentthe outermost ends of the horizontal passages 47 for purposes to bebetter understood in the foland it is therefore necessary to provide asemi-circular portion 52 adjacent the middle of the weight supportingbar to skip or otherwise free the tube 35 during the reciprocatingactions of the weight supporting bar. A weight member 53, of annularformation, encircling the tube 35 carries hook members 54 of theconfiguration shown designed for detachable connection within the eyesof loops 55 formed adjacent the points of intersection between thehorizontal portions of the weight supporting bar 51 and the extremitiesof the semi-circular portion 52.

The uppermost pulley 43 has the innermost ends of cords or cables 56oppositely wound thereabout and guided in alignment therewith, incidentto the formation of guide recesses 17 within the outermost upwardly andobliquely inclined extremities of the cross arm. Aeroplanes, Zeppelins,gliders and other representations of air craft are to be attached orotherwise suspended from the outermost depending ends of the cords orcables 56 after the manner employed in the previously described forms ofmy invention.

The invention is susceptible of various changes in its form, proportionsand minor details of construction, and the right is herein reserved tomake such chagnes as properly fall within the scope of the appendedclaims.
